Struct Version 

pub struct Version { /* private fields */ }

Methods from Deref<Target = Version>

pub fn cmp_precedence(&self, other: &Version) -> Ordering

Compare the major, minor, patch, and pre-release value of two versions, disregarding build metadata. Versions that differ only in build metadata are considered equal. This comparison is what the SemVer spec refers to as “precedence”.

Example

use semver::Version;

let mut versions = [
    "1.20.0+c144a98".parse::<Version>().unwrap(),
    "1.20.0".parse().unwrap(),
    "1.0.0".parse().unwrap(),
    "1.0.0-alpha".parse().unwrap(),
    "1.20.0+bc17664".parse().unwrap(),
];

// This is a stable sort, so it preserves the relative order of equal
// elements. The three 1.20.0 versions differ only in build metadata so
// they are not reordered relative to one another.
versions.sort_by(Version::cmp_precedence);
assert_eq!(versions, [
    "1.0.0-alpha".parse().unwrap(),
    "1.0.0".parse().unwrap(),
    "1.20.0+c144a98".parse().unwrap(),
    "1.20.0".parse().unwrap(),
    "1.20.0+bc17664".parse().unwrap(),
]);

// Totally order the versions, including comparing the build metadata.
versions.sort();
assert_eq!(versions, [
    "1.0.0-alpha".parse().unwrap(),
    "1.0.0".parse().unwrap(),
    "1.20.0".parse().unwrap(),
    "1.20.0+bc17664".parse().unwrap(),
    "1.20.0+c144a98".parse().unwrap(),
]);
